An air compressor with an oil content of less than 0.01 mg per cubic meter can be called an oil-free air compressor. In other words, this value is 0.01ppm, that is, 0.01 parts per million, which can be said to be almost negligible.
For example, if you spread a drop of oil evenly into a very large room, the oil content in the room is probably close to this figure. Therefore, when the gas discharged from an air compressor is less than this level of oil, the industry recognizes that it is oil-free.
For ordinary oil-injected screw air compressors, the exhaust oil content is generally about 3 mg per cubic meter, which is hundreds of times higher than the 0.01 standard, so it can only be regarded as an oil machine.
What about the water-lubricated air compressor? It uses water instead of oil to seal the rotor and take away the heat. Because the entire compression process does not use oil at all, the discharged gas naturally does not contain oil, and the oil content can easily be less than 0.01 mg per cubic meter, or even lower. In other words, the water-lubricated air compressor is naturally suitable for reaching the oil-free standard in principle. It does not need to be pulled hard by adding a filter at the back, but there is no oil from the source. This is why food, medicine, electronics, which are particularly sensitive to air, are increasingly choosing water-lubricated air compressors.
The air compressor is designed to provide high-pressure air compression equipment for the hole blowing machine, and its performance directly affects the operating efficiency and stability of the hole blowing machine. The following is a detailed introduction to the air compressor for the hole blowing machine: 1. main types and characteristics of air-cooled screw air compressor:
Scroll type oil-free model: through high-precision processing and sealing design, completely avoid oil pollution, suitable for high air cleanliness requirements of the scene. Single screw type oil-free model: the use of water instead of oil for lubrication and cooling, the need to regularly replace the circulating water and clean up the scale, maintenance complexity is higher than the scroll type, but can provide oil-free compressed air.
Permanent magnet variable frequency screw air compressor has significant advantages in energy saving efficiency and operation stability through technological innovation. Granklin air compressor adopts water-lubricated single screw technology, combined with permanent magnet frequency conversion control, to provide users with more efficient and reliable compressed air
There are many possible reasons for the low voltage shutdown of the air compressor. The following are some common troubleshooting points and solutions: poor contact of the power cord: the power cord may be open or loose, resulting in unstable voltage. Should be checked and re-fixed
Gas volume, or flow rate, is usually expressed in the following units in air compressors and other gas-related equipment: cubic meters per minute (m & sup3;/min): This is a common unit of gas flow, especially in industrial applications. It says every minute through
The general air pressure in the factory is not a fixed value, but will be adjusted according to the specific equipment requirements and production process. However, some common reference ranges and standards can be provided to aid understanding. Air pressure standard of air compressor: often in the factory
Air compressor plays a vital role in the enterprise, it mainly solves the problem of power demand for compressed air in the production process. Specifically, the enterprise problems solved by the air compressor can be summarized into the following aspects: 1. Provide power source air pressure
The core difference between micro-oil and oil-free air compressors and the technical advantages of Glanklin water lubricated screw air compressors In the industrial and medical fields, the selection of air compressors should be strictly distinguished according to the quality requirements of gas consumption. Micro-oil air compressor and oil-free air compressor in the compression principle, output gas
When discussing whether it is more cost-effective to choose frequency conversion or power frequency air compressor when compressed air consumption is not much, we need to consider a number of factors, including the operating cost of the equipment, the convenience of maintenance, and the control of air quality.

The safety inspection of air compressors involves many aspects to ensure the normal operation of the equipment and the personal safety of users. The following are the air compressor safety inspection items based on multiple authoritative sources: 1. electrical system inspection grounding and leakage inspection: indeed
